Water dispersion system for industrial dust suppression
Dust-filled air that occurs when crushing or transporting bulk goods, can be cleaned by spraying with fine water droplets. Ordinary water nozzles fail to generate the same spectrum of drops and, most importantly, the necessary fineness. This results in the equipment becoming wet, whilst the dust remains.

With the DUSTEX® system, water is ripped apart by two component nozzles using an air-stream moved by ultrasonic oscillation into drops of 5 to 20 µm in size.

With the fineness of the drops, the number of drops and the surface affinity for dust, and therefore the effect, increases disproportionately. The dust can be moistened and, through suppression, be transported away with the main material flow.

VSR company history

After its founding in 1975, VSR quickly developed into an internationally operating company– partly because our strengths are purposeful advice and problem-solving from the start.

With the VSR BLASTER® air cannon, we have also developed pioneering technology; the cement industry, in particularly, quickly recognised the potential of this product, which still sets the standard. The company’s leading position has been maintained through continuous, customer-oriented development. However, we are still able to keep spare part compatibility.

In 1988 we faced a new challenge with the DUSTEX® Dispersion Systems for dedusting: environmental protection. With special nozzle technology and problem-oriented system designs, our systems achieve the highest effectiveness with minimal use of water. Expansion of the product portfolio by water spraying and sprinkling systems and the mobile fog blower make it possible to solve nearly all dust problems. The fact that authorities and government agencies today demand qualified water spraying systems and dispersion systems as the standard of technology in accordance with the German Air Pollution and Control Regulation “TA-Luft”, is due to the pioneering work of VSR. Development continues – a research project under the patronage of the Federal Ministry of Education and Research is currently in progress with the aim to also reduce considerably very fine dust particles.

With optimisation of bulk material conveyor belt transport, the VIBREX® conveyor belt scrapers, LINEX® conveyor belt centralizing idlers and CAREX® segment block system for chute sealing are important tools that have been developed further and proven their worth in a variety of applications over the course of time.

The VIBMATIC® vibratory stress reduction procedure takes a special position
as the company’s first product; it is this product that gave it´s name to VSR: Vibration Stress Reduction. The process is a true alternative to stress-relief annealing in many respects: internal tension that would result in unacceptable warping during mechanical processing is simply “vibrated away” with the treatment. Handling, energy use and logistics can be minimised, thus creating a significant reduction of production costs. Well-known, large corporations have also taken notice of these advantages that are completed by the extensive, environmental protection. In the current 6th generation of equipment, a modern computer controls the vibration generator; this also enables easy creation of logs and reports for the treatment. A research project was also recently conducted in combination with this product, subsidized by the Federal Ministry for Economic Affairs and Energy.
